FEP Resin (DS618) for jacket of high speed and thin wire & cable
FEP DS618 series is a melt-processible copolymer of tetrafluoroethylene and hexafluoropropylene without additives that meets the requirements of ASTM D 2116. FEP DS618 series has good thermal stability, outstanding chemical inertness, good electrical insulation, non-aging characteristics, exceptional dielectric properties, low flammability, heat resistance, toughness and flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption and excellent weather resistance. DS618 series has high molecular weight resins of low melt index, with low extrusion temperature, high extrusion speed which is 5-8 times of ordinary FEP resin.

Mainly in the MTR transport vehicles, automatic switching equipment, well test equipment, flame alarm systems, high-rise building, fire regional wires, cables, computers, communication networks, electrical fields, particularly applicable for high-speed extrusion small-caliber wire insulation material.It is more economical when used in where no high stress cracking resistance is required.
The processing temperature should not exceed 420℃, to prevent toxic gas from releasing.
